I Specification of Letters Patent. Application filed October 17, 190s. Serial no. 45$,i4s. y

Patented Oct. 126,1909I Toallwhom it may concern: J v

Be-itknownthat I, "WILLIAM C.'P.AUL, a citizen of the United States, residing ,at

7 New York, N. Y., have invented certain new and useful Improvements in Hydrocarbon- Mixers, of which the followingv is a full, clear, and exact description.

My invention relates to improved mixing devices. a

"My improved mixer maybe very successfully employed wherever it is desired to effectively mix volatile liquids with air. For

' ,example, it may be used with great efiiciency upon induction pipes for engines of the internal combustion type whereby from a such use a perfect mixture of liquid hydrocarbon and air is guaranteed; Although the aim of the present day vaporizers and carbureters, so-calledfis to pro- 20 duce a mixture of gas and air and to measure the same so as to preserve the relative proportion of one to the other under varying demands,.great difiicult-y is experienced in securing a complete mixture of the liquid fuel with the air. Now, by my invention this complete mixture is effected and that end is attained by a construction which is exceed ingly simple, inexpensive and durable.

In the accompanying drawings, I have shown my invention in the preferred form, in whieh- Y v Figure 1 is a longitudinal sectional view. Fig. '2' is across section on the line X-X. looking down. o

1 is a casing preferably cylindrical in form, having an inlet 2 and an outlet 3'0 relatively reduced diameter.

4 is a disk-like plate suitably-secured.

within the casing 1 and extending transversely of the same. 5 is' another similar plate located, in said casing and spaced apart from the plate t,

6-6 are-tubes carried bythe plate projecting toward-the plate 5.

7--7' aretubes carried by the projecting toward the plate 4.

Theqtub'esor nozzles 6 -7'are so arranged -relatitfely to each other that theydo not interfere and the upper end of each tube 6 extends slightly above or overlaps the "lower end of each tube- 7. Each tube Ga -6' directs plate 5 and above the plate 5. screen may be made mixture.

4 and Y ts jet against a solid part of theuplate standin any desired manner and when employed it will perform the functions hereinafter at tributed to the same.

The case may be made insections, but the construction thereof-is immaterial. Thefinlet 2 and outlet 3 may be provided with any suitable form of coupling devices whereby the mixer maybe readily connected to an induction pipe or other conduit. In the drawings I have shown by arrows the direcwill be seen by these arrows, imperfectly. mixed gas enters through the inlet 2 into the lower 'part of the chamber 1. It is then divided up and conducted through the'several nozzles 6-6 in the form of a gurality of jets which impinge against a solit part of the overstanding plate 5, by which it is de' flected and caused to pass down through the space between the overlapping ends of the tubes or nozzles 6-7. It then enters the tubes 77 and is passed through the same in the form of jets corresponding in numbe! to the number of tubes 77. here a screen 8vis used, the gas will thenpass through said'screen into the upper part of the chamber 1 and finally out through the outlet 3. I

It will be seen from the foregoing that the course which the gas is obliged to fol-, low is so tortuous and the several jets of gasjhave been so agitated by the deflecting walls that by the time said gas is passed through the reve "sely arranged gas passages 67 any previously unmixed fuel in the form of vapor will become thoroughly mixed with. the air so that the gas as it proceeds from the outlet 3 is in the form of avperfect Thev function of the screen 8 when employed is two-fold. It first serves to supplement the action of the previously described parts in perfecting the mixture, and; second, it serves to prevent back-firing into the space to'the rear of the screen. It will be observed that the gas is in a certain sense' contracted as it enters each vortex at the.

entrance to each .pipe. 6. It is then permitted to expand as it is dischargedfrom saidpipes, and is again contracted where it en- T ters the pipes 7-7, and is again permitted 9 to expan where it emerges therefrom. Thisrepeated contraction and expansion of the gasoperates most effectively to secure the esired mixing effect. As will ,be seen in Fig.- 2, a large number of pipes 6 '6 .are'em- 9 tion of travel of gas through the mixer. As 4 to modification.

I back, and whereby also during use a suih 'ployed', it being desirable to provide in the sum of the cross-sectional areas of said pipes a fcrosssectional area that will correspond to or be slightly greater than the cross-sectional area of the inlet 2, whereby no injurious choking effect will be produced.

While the best results are obtainable by "substantially the means shown in the draw ings and previously described, it should be understood that my invention is susceptible Forexample, I apprehend that very beneficial results may be obtained by a modified; arrangement in which the jet principle is availed'of even though the particular number, size and arrangement of.

'pipes'be very materially modified. Indeed, 1

in some instances it might be possible to omit e ther one or the other of the sets of 9' are small drip ports arranged, in the late 4 and connectin the s ace above said,

plate with the space below the same whereby any condensation in said space may run cient quantity of air may pass into the space farounsd'the base of the pipe 6 to volatilize let, an outlet, within said chamber and extending transversely thereof, including any fluid condensation that may occur. Similar drip orts may be provided in plate 5. Obviously the number of transverse plates 45 maybe increased if desired.

Obviously this principle and construction may be employed for mixing any fluid .sub-

stances.v

2. In a mixer, an lnclosed chamber, an lnlet and an outlet therefor, two transversely arranged perforated plates carried. in said chamber, the perforations in one plate being out of line wit t 1e perforations in the other plate,- and es carried by one plate around the/pe' rations therein and arranged to dits toward an imperforate part of the er plate whereby gas passing through said tubes will be deflected.
